THe bigger Question is: Is it possible, to send the Cam to sleep between Shots? Example: I want a Picture every 10 Minutes for about 24 hours. When it goes to sleep after every shot and wakes up himself, then it is possible.

I think most reliable way of capturing 24 hours or more is to use an external battery pack or mains power and let the camera stay on for the whole time without sleeping.

I've used GH2 with 12v car battery, 12v to 9v transformer, a DC coupler and a JJC intervalometer. Depending on car battery AH capacity, it can stay on for up to a week. Even more is possible with very large 12v batteries.

When using lead acid batteries, one thing to remember is to use a drain protector between camera transformer and battery, or else the battery might get completely drained and can't be recharged anymore. Cheap drain protectors are often available at stores that sell 12v car refrigerators and other car accessories.

Of course other kinds of high-capacity external batteries will also work well, car batteries are just one of the most affordable options.

The Cam goes to sleep after each shot, when the interval is longer as 5 minutes. This is necessery for example if you shoot all 15 oder 60 minutes 1 PIcture the whole day or night. Otherwise it would be finish after 4 hours (Battery empty).

YOu have to import it to a Video-Software like Premiere Pro to create a Movie. But it should be easy.

Are multiple exposures possible in timelapse mode (not with external timer)? I started playing around with the timelapse function but couldn't figure out if it is my lack of knowledge about the cam or if it is simply not possible.

@jfilmmaker Depends on the shot interval you select and the playback speed. I would recommend 2 second intervals to preserve the 180 degree shutter rule. 16:9 GH3 RAWs take up around 14MB each, so 64GB = 65536MB or 4681 frames. That is over 3 minutes of footage at 24fps playback. In my opinion you would be best served to invest in the battery grip, the camera will literally run all day long on two batteries and the electronic shutter uses hardly any power.

As far as I understand, 180 degree shutter angle rule is mostly about creating motion blur at 24/25 fps that helps to get (specific kind of) perception of movement for subjects that viewers are used to seeing in realtime. Human subjects especially tend to move at a set range of speeds, and motion blur they create at 1/48 or 1/50 shutter speed is close to what many perceive as "natural". This can be tested with moving people, faces changing expressions etc. So for example, at 50 fps I'd still use 1/50 shutter speed to keep that same motion blur, even if it is equivalent to 360 degree shutter angle.

Since timelapse is not perceived as realtime, and different interval and shutter speed combinations create different kind of perception of movement depending on the subject, getting aesthetically pleasing movement and motion blur is more complicated. I'd say equivalent of 360 degree shutter is a better try in many cases. There are exceptions of course.

Funny thing about capturing slices of time is that the further you go from trying to capture realtime in human perspective, the more of a mindscrew it becomes...

Hey guys, I'm having trouble getting my Macbook Pro, OS10.8.2, to read the Panasonic GH3 specific .RW2 raw files so that I can make a timelapse video. SilkyPix that game with GH3 can read the .RW2 files, but no other Mac application that I have can also read them, and no application I have can read and assemble them in bulk ala movie. Anyone have advice on this???

@vicharris the GH3 has a miniature setting, which mimics the use of a tilt shift lens (blur is applied to the top and bottom of the footage) and frames are dropped to create the timelapse effect, the miniature mode also boosts saturation a little, all of this can be done quite easily in post, but in cam can look effective, best used when looking down at wide landscapes.
PS. There are no dumb questions :)

@vicharris, it put's your focal point at one area while the rest is essentially blurred/out of focus. You just need to be far enough back where it makes it looks good with everything scaled down. Commercially, I've seen this used on an AllState commercial and also in the movie Social Network where the twins lose their rowing competition. There's a post here with some examples from GH2 owners here.

this TL world is very dense, I have so many questions... but I'll go easy:
given same size of frame, is there any difference when keyframing a motion/animating a (tif) image sequence or a (uncompressed) video file in after effects (or other composing apps)?

The bigger IQ loss I noticed was on roundtrip conversion from MOV to AVI; which I end up doing with iFFmpeg (had some issues with Quicktime); and of course from final master output to x264, anyway I used this A2 handbrake preset,
Is there natively for mac a better way of transcoding MOV to AVI and viceversa without IQ loos?
I found TEncoder but win version only and can only run it 32 bit mode...
